Abstract
The invention discloses a refining ladle on-line argon adjustment method which adjusts the argon quantity in time according to the molten steel surface rolling condition to achieve the optimal effect and enhance the molten steel quality. The method comprises the following steps: connecting an argon branch pipeline from a ladle argon pipeline to a refining buggy ladle, wherein the argon branch pipeline is provided with a diaphragm adjusting valve; after the refining furnace finishes smelting and the buggy ladle runs from the work position to the waiting position to prepare soft blow, opening the argon branch pipeline, manually adjusting argon on site by using the diaphragm adjusting valve, and adjusting the soft blow of the molten steel in the ladle, thereby achieving the optimal effect of soft blow creepage without rolling; meanwhile, closing the computerized argon control on the ladle argon pipeline; and finely adjusting the argon through the computer on the ladle argon pipeline according to the argon point soft blow condition of the molten steel level to keep the optimal effect of soft blow creepage without rolling. According to the method, the argon quantity is adjusted in time according to the molten steel surface rolling condition, thereby saving the soft blow adjusting time, saving the argon consumption and enhancing the molten steel quality.
Description
Technical field
The invention belongs to field of metallurgy, the argon gas control method while relating to a kind of steel-making, specifically a kind of refining ladle is adjusted argon gas method online.
Background technology
Refining furnace is when the soft blow of molten steel argon gas, buggy ladle is in waiting for position, operative employee crosses PLC system control argon gas valve platform in industrial computer bypass and carries out the adjusting of argon gas amount, this control method has two drawbacks: one, because operative employee's sight line reaches ladle liquid level, need blast-furnace man and operative employee to cooperatively interact and could regulate in time steel ladle bottom argon blowing tolerance, reach best soft blow effect, otherwise need operative employee's commute repeatedly to check that then soft blow effect return industrial computer and adjust, time waste is more; Two, because each ladle service condition is different, the effect of gas permeable brick is not quite similar, and argon gas Fa Taishi unit argon gas regulates, suddenly big or suddenly small while causing soft blow, affects steel quality.
Summary of the invention
The problem existing in order to overcome prior art, the object of this invention is to provide a kind of refining ladle and adjusts online argon gas method, and the method is adjusted argon gas amount in time according to the molten steel surface situation of seething, and saves the time that soft blow is adjusted; Save argon gas usage quantity; Improve steel quality.
The object of the invention is to be achieved through the following technical solutions:
Refining ladle is adjusted an argon gas method online, it is characterized in that: the method is adjusted argon gas amount in time according to the molten steel surface situation of seething, and reaches best effect, improves steel quality; Concrete steps are as follows:
1), on ladle argon gas pipeline and connect an argon gas and divide pipeline to refining steel to hire a car, at argon gas, divide and on pipeline, be provided with diaphragm regulating valve;
2) refining furnace is after smelting finishes, and buggy ladle reaches and waits for that position prepares a soft blow from working position, at this moment opens argon gas and divides pipeline, by diaphragm regulating valve on-site manual, regulates argon gas, regulates the soft blow of molten steel in ladle, reaches that soft blow is wriggled and the best effect that do not seethe; Close the argon gas of ladle argon gas pipeline computer controls simultaneously;
3) according to the argon gas point soft blow situation of liquid steel level, by ladle argon gas pipeline computer fine setting argon gas, keep soft blow to wriggle and the best effect that do not seethe.
In step 1) of the present invention, working properly for guaranteeing, Accident prevention occurs, and at argon gas, divides on pipeline the using and the reserved two cover valving are set, and every cover valving is two Stainless Steel Ball Valves and a diaphragm regulating valve.
The present invention's Bing Jie mono-road argon gas to refining steel on existing ladle argon gas pipeline is hired a car, refining furnace is after smelting finishes, buggy ladle reaches and waits for position preparation soft blow from working position, at this moment open on-site manual and regulate argon gas, with diaphragm regulating valve, carry out the soft blow of molten steel in manual regulation ladle, close the argon gas of computer simultaneously and control.Then according to the argon gas point soft blow situation of liquid steel level, finely tune argon gas.
The invention has the beneficial effects as follows:
when soft blow, can finely tune by wafer type valve, reach that soft blow is wriggled and the best effect that do not seethe improves steel quality;

Fig. 2 is argon gas pipeline principle schematic in the present invention.
Embodiment
Refining ladle is adjusted an argon gas method online, and the method is adjusted argon gas amount in time according to the molten steel surface situation of seething, and reaches best effect, improves steel quality; Concrete steps are as follows:
1), on ladle argon gas pipeline 1 and connect an argon gas and divide pipeline 2 to refining steel hired car 3, at argon gas, divide and on pipeline, be provided with diaphragm regulating valve 4; Working properly for guaranteeing, Accident prevention occurs, and at argon gas, divides on pipeline the using and the reserved two cover valving are set, and every cover valving is two Stainless Steel Ball Valves and a diaphragm regulating valve.
2) refining furnace is after smelting finishes, buggy ladle reaches and waits for position preparation soft blow from working position, at this moment opens argon gas and divides pipeline 2, by diaphragm regulating valve on-site manual, regulates argon gas, by argon gas variable valve platform 5, regulate the soft blow of molten steel in ladles, reach that soft blow is wriggled and the best effect that do not seethe; Close the argon gas of ladle argon gas pipeline 1 computer controls simultaneously.Argon gas variable valve platform 5 is the topworkies that regulate argon gas.
3) according to the argon gas point soft blow situation of liquid steel level, by ladle argon gas pipeline computer fine setting argon gas, keep soft blow to wriggle and the best effect that do not seethe.
The present invention's Bing Jie mono-road argon gas to refining steel on existing ladle argon gas pipeline is hired a car, and by on-site manual, regulates argon gas, carrys out the soft blow of molten steel in manual regulation ladle with diaphragm regulating valve, then according to the argon gas point soft blow situation of liquid steel level, finely tunes argon gas.Reach best effect, improve steel quality.
